1. An analytical test strip for use with a test meter, the analytical test strip comprising:
- a first insulating layer with a first insulating layer upper surface;
a first electrically conductive layer disposed on the first insulating layer upper surface and including;
a first electrode portion; and
at least one electrical contact pad in electrical communication with the first electrode portion;
a patterned spacer layer disposed above the first electrically conductive layer and including;
a distal portion defining a bodily fluid sample-receiving chamber therein that overlies the first electrode portion; and
an insulating proximal portion with an upper surface and a second electrically conductive layer disposed thereon, the second electrically conductive layer including;
an interlayer contact portion; and
an electrical contact pad;
a second insulating layer disposed above the patterned spacer layer and having a second insulating layer lower surface;
a third electrically conductive layer disposed on the third insulating layer lower surface and including;
a second electrode portion; and
a proximal portion overlying the interlayer contact portion,wherein the second electrode portion is disposed overlying and exposed to the sample-receiving chamber and in an opposing relationship to the first electrode portion, andwherein the proximal portion of the third electrically conductive layer is operatively juxtaposed with the interlayer contact portion of the second electrically conductive layer such that there is an electrical connection between the second electrode portion of the third electrically conductive layer and the electrical contact pad of the patterned spacer layer during use of the analytical test strip.

Abstract
An analytical test strip (“ATT”) for use with a test meter includes a first insulating layer, with a first insulating layer upper surface, and a first electrically conductive layer (“ECL”) disposed thereon. The first ECL includes a first electrode portion (“EP”) and an electrical contact pad in electrical communication with the first EP. The ATT also includes a patterned spacer layer disposed above the first ECL that includes (i) a distal portion defining a bodily fluid sample-receiving chamber therein that overlies the first EP and (ii) an insulating proximal portion with an upper surface having a second ECL disposed thereon. The second ECL includes an interlayer contact portion and an electrical contact pad. A third ECL of the ATT includes a second EP and a proximal portion that overlies the interlayer contact portion. The second EP is disposed overlying and exposed to the sample-receiving chamber in an opposing relationship to the first EP.

12. A method for determining an analyte in a bodily fluid sample, the method comprising:
-
introducing a bodily fluid sample into a sample-receiving chamber of an analytical test strip, the sample receiving chamber having a first electrode portion of a first electrically conductive layer and a second electrode portion of a third electrically conductive layer therein, the first electrode portion and the second electrode portion being in an opposing relationship; measuring an electrical response of the first electrode portion and the second electrode portion via an electrical contact pad of the first electrically conductive layer and via an electrical contact pad of a second electrically conductive layer of a patterned spacer layer of the analytical test strip, the patterned spacer layer being disposed between the first electrically conductive layer and the third electrically conductive layer and wherein the electrical contact pad of the first electrically conductive layer and the second electrically conductive layer are configured in a unidirectional stacked relationship, and wherein the second electrode portion is in electrical communication with the electrical contact pad of the second electrically conductive layer; and determining the analyte based on the measured electrical response. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
